Dest 192.168.2.0/24 via 10.0.0.2
Private IP ranges (like 10.0.0.0/8 , 172.16.0.0/12 , and 192.168.0.0/16 ) are for internal use only. They cannot be routed across the public internet. allows devices with private IPs to access the internet by having the router replace their private source IP with its own public IP before forwarding packets. In NetPractice, you'll encounter scenarios where internal networks need to reach external ones—this is where routing and NAT come into play.
NetPractice requires you to calculate boundaries quickly. Use this binary scale for a single octet to convert masks instantly: Bit Position Common Subnet Mask Conversions /24 = 255.255.255.0 (Block size: 256) /25 = 255.255.255.128 (Block size: 128) /26 = 255.255.255.192 (Block size: 64) /27 = 255.255.255.224 (Block size: 32) /28 = 255.255.255.240 (Block size: 16) /29 = 255.255.255.248 (Block size: 8) /30 = 255.255.255.252 (Block size: 4) 3.
